Supportive device



FIG. 1 is a front, left perspective view of a supportive device showing my new design;

FIG. 2 is a rear, right perspective view thereof;

FIG. 3 is a front view thereof;

FIG. 4 is a rear view thereof;

FIG. 5 is a top view thereof;

FIG. 6 is a bottom view thereof;

FIG. 7 is a left side view thereof; and,

FIG. 8 is a right side view thereof.

The grayscale shading in the figures, which may show shadows and reflections, is for the purpose of illustrating contour, not any particular color. The relatively light faded portions, showing the wheels and the underside, form no part of the claimed design.
